SCHNEIDER, OF ST. LOUIS, MISSOURI,

SAFE-DOOR.

Specification of Letters Patent.

Application led August 31, 1907.

Patented Dec. 1, 1908.

Serial No. 390,954.

To all whom 'it may concern:

Be it known that I, JAMES M. ALLEN, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Safe-Doors, of which the following is a specification, containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to safe doors, my object being to construct a simple, inexpensive two-piece door for safes, through the center of which passes a spindle utilized for actuating the locking mechanism arranged in a recess formed in the inner face of the inner piece of the'door and said spindle being provided with a circular head occupying a corresponding recess formed in the outer piece, which -arrangement prevents any longltudinal movement of the spindle when arranged in the door.

To the above purposes, my invention consists in certain novel features of construction and arrangement of parts, which will be hereinafter more full set forth, pointed out in the claims, and il ustrated in the accompanying drawings, in which Figure 1 is a vertical section taken through the center of a portion of a safe of spherical form, and equipped with a door of my improved construction; Fig. 2 is a vertical section taken on the line 2-2 of Fig. 1; Fig. 3 is a perspective view of the shaft or spindle which passes through the center of the door, and which is utilized for operating the locking bolt and combination mechanism.

Referring by numerals to the accompanying drawings 1 designates the front wall of the safe, through which is formed the circular opening which is closed by rnyim roved door, and the central portion of sai opening is provided with a suitable thread 2; and the end of the opening, adjacent the outer surface of the safe wall, is enlarged, as designated by 3, there being a shoulder 4 formed between said enlarged portion and the threaded ortion.

Forme integral with the Wall 1 of the safe, around the inner end of the opening, is a flange 5, in which is formed a recess 6, in which engages the end of the locking bolt carried by the safe door.

The door is constructed in two parts, the

combined thickness of which is approximately equal to the thickness of the wall of the safe in which the opening is formed; and the outer member 7 of the door is provided on its edge with an integral flange 8, which, when the door is closed, occupies the enlarged outer end 3 of the opening in the safe.

The outer face of the member 7 is constructed so as to conform to the contour of the wall of the safe, and passing through the center of said member is a circular opening 9, which communicates with a large circular opening, or recess 10, formed in the rear face of said member 7.

The inner member 11 of the door is in the form of a disk, or circular block, and is rigidly xed to the member 7 by screws 12, or in any suitable manner g and the periphery ofV said inner member, together with that portion of the periphery to the rear of the flange 8 of the member 7, are provided with a thread 13, which is adapted to engage the thread 2 for-med in the door opening.

Formed in the rear side of the member 11 is a large circular opening, or recess 14; and formed through the flange between this opening and the outer edge of the member 11 is an aperture 15, which coincides with the recess 6 when the door is closed by being screwed into the door opening to its limit of movement.

Formed through the center of the member 11 is an opening 16, which is in alinement with the opening 9, and arranged for rotation in said alined openings is a shaft or spindle 1 7, with the center of which is formed integral a circular head 18, which snugly iits within the opening 10. The outer end of this shaft or spindle 17 is reduced in diameter, as designated by 19, and extends beyond the face of the member 7, and receives a small disk 20, which is manually engaged when the shaft or spindle is rotated.

Formed on or fixed to the rear end of the shaft or spindle 17 is an eccentrically arranged pin 21, on which is journaled the lower end of a locking bolt 22,lthe outer end of which passes through the opening 15 and engages in the recess 6 when the door is locked.

The recess or opening 14 is designed to receive the combination mechanism, (not shown,) which controls the locking and unlocking of the door, and which combination mechanism may be actuated by a partial or complete rotation of the shaft or spindle 17.

The shaft or spindle 17' ts snugly in the openings 9 and 16, and the head 118 fits snugly in t'he opening 10, thus effectually preventing the introduction of a liquid eX- plosive through the center of the door, and the head 10 positioned between the members 7 and 11 prevents the shaft and spindle from being driven or pulled through the door.

The outer face of the member 7 lies flush with the outer face of the wall of the safe, and the thread formed on the members 7 and 1 1 snugly fitting the thread in the door opening, prevents an explosive in liquid or powdered form from being forced between the edge of said door and the edge of the door opening.

A door of my improved construction is simple in construction and operation, comprises a minimum number of parts, and is particularly adapted for use in connection with safes of spherical form.

I claim 1. The combination with a safe having a screw' threaded door opening of a screw threaded door constructed in two parts, adapted to occupy the door opening, locking means carried by the inside of the inner part of the door and adapted to engage the body of the safe, there being a recess formed in the outer part of the door adjacent the front face of the inner part, a shaft passing through the center of the door for actuating the locking means, and a circular head integral with the shaft and occupying the opening in the outer part of the door.

2. A safe door, comprising a pair of circular blocks rigidly fixed to one another, there being a recess formed in the inner face of the inner block, locking means arranged in said recess and adapted to engage the body o f the safe, there being a circular recess formed in the rear face of the outer block, a shaft passing through the centers of both blocks for actuating the locking means, and a circular head integral with the shaft and occupying the recess in the outer block.

3. A safe door, com rising a pair of circular blocks' rigidly fixe to one another, there being a recess formed in the inner face of the inner block, locking means arranged in said recess and adapted to engage the body of the safe, there being a circular recess formed in the inner face of the outer block, a shaft passing through the centers of both blocks for actuating the locking means, a circular head integral with the shaft and occupying the recess in the outer block, and a disk xed on the outer end of the shaft and bearing against the face of the outer block.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.

JAMES M. ALLEN.
